Product Description
Our White Label No Leakage Silicone Liquid Flow Control Dispensing Valves are precision-engineered from 100% FDA-compliant, food-grade liquid silicone rubber (LSR) to deliver superior dispensing performance across a wide range of viscous liquids—including ketchup, honey, mayonnaise, and syrups. Manufactured through high-precision liquid silicone injection molding, these valves feature a flexible slit-membrane design that enables smooth, one-way dispensing while preventing drips, backflow, or leakage. Each valve is designed for optimal flow control, ensuring consistent portioning with minimal effort. With excellent temperature resistance (–40 °F to 450 °F), chemical stability, and reusability, our dispensing valves meet LFGB, FDA, and RoHS compliance standards, making them the ideal choice for food packaging and dispensing solutions.
We provide full OEM and white label solutions, including custom slit geometry, sizes, shore hardness, and branding options, to meet the unique requirements of your product line.

Quality Assurance
Quality assurance for silicone dispensing valves focuses on safety, durability, and consistency. All raw silicone materials undergo strict incoming inspection to verify 100% BPA-free, FDA, and LFGB compliance. During production, advanced precision LSR injection molding machines ensure consistent membrane thickness and dimensional accuracy. Testing includes:
- Leakage and flow tests to guarantee zero-drip performance
- Tensile and compression tests to validate elasticity and durability
- Aging and temperature resistance tests in chambers up to 450 °F
- Visual and dimensional inspections with 3D measurement systems
Every production batch is traceable and undergoes final QC checks in a cleanroom-controlled environment. Our facility is ISO 9001 and IATF 16949 certified, ensuring compliance with global standards.
